Wormholes could bend light like black holes do

If wormholes exist, they could magnify up to 100,000 times the light of distant objects – and this could be the key to finding them.

Wormholes are theoretical funnel-shaped portals through which matter (or perhaps spacecraft) could travel great distances. To imagine a wormhole, suppose the whole universe is a sheet of paper. If your starting point was a point at the top of the sheet and your destination was a point at the bottom of the sheet, the wormhole would appear if you bend that sheet of paper so that the two points meet. You can traverse the entire sheet in an instant, rather than traversing the entire length of the sheet.
